## Problem 414 Truss by Method of Joints

**Problem 414**

Determine the force in members AB, BD, and CD of the truss shown in Fig. P-414. Also solve for the force on members FH, DF, and DG.

## Problem 413 Crane by Method of Joints

**Problem 413**

Determine the force in each member of the crane shown in Fig. P-413.

**Solution 413**

## Problem 412 Right Triangular Truss by Method of Joints

**Problem 412**

Compute the force in each member of the truss shown in Fig. P-412. If the loads at B and D are shifted vertically downward to add to the loads at C and E, would there be any change in the reactions? Which members, if any, would undergo a change in internal force?

## Problem 411 Cantilever Truss by Method of Joints

**Problem 411**

Determine the force in members AB, AC, BD, CD, and CE of the cantilever truss shown in Fig. P-411. If the loads were applied at C and E instead of at B, specify which members would have their internal force changed.
